The effect of copper ions on the motility of human sperm was studied in vitro to determine whether copper is toxic to sperm. Sperm samples from 30 men of proven fertility who had high quality sperm were collected, separated from the seminal fluid, and resuspended in Menezzo, a chemical medium designed to resemble the secretions of the Fallopian tubes.

Fluid was collected from the Ponch of Douglas at laparoscopy or laparotomy in 104 women. Macrophages were always present. The Schiff's histochemical reaction was positive inside the cytoplasm in cases of pelvic endometriosis in our study. This technique allows characterization of the cell population in cases of chronic pelvic inflammation and confirmation(More)
The recent detection of immunoreactive POMC derived peptides in the male reproductive tract raised the possibility that these hormones might regulate reproductive function. In addition, a variety of studies suggested that POMC derived peptides have paracrine effects in the testis. In this present study, after HCG addition to the organ culture medium,(More)
A gonadotrophin-like material (GLM) was observed by immunocytochemical methods in prepuberal guinea pig testes, not only on Sertoli and interstitial cells, but also on spermatogonia and spermatocytes. The intracellular cytoplasmic localization of GLM is discussed in relation to the receptor internalization theory. Variations between young and adult animals(More)
The distribution of opioid peptides is of interest in the rat testes, because the presence of opiate binding sites strongly supports the hypothesis of paracrine function for these peptidergic factors. Testes of Wistar albino rats between birth and adult stage were examined immunocytochemically for enkephalins, dynorphin, and alpha neoendorphin. The presence(More)
A survey of indications and results of cryopreserved testicular spermatozoa has been performed by French Federation of CECOS from 1 January 96 to 31 December 97. 340 sperm cryopreservations (264 with testicular sperm) has been performed: 252 in excretory azoospermia, 88 in non obstructive azoospermia. 30 cycles of ICSI was performed with frozen-thawed(More)
